              <p>
                This will allow pkg-config to use its internal version of
                Glib because an external version is not available in LFS.

            <dd>
              <p>
                This option prevents the build system from using compiler
                flags which cause build failure when building with GCC 6.

                This option disables the creation of an undesired hard link
